Chinese cold sesame noodles are a classic, addictive dish: springy noodles coated in a rich, nutty sesame sauce, served chilled or at room temperature with crisp vegetables and a hint of spice. They’re perfect for hot weather, easy to meal-prep, and can be made vegetarian or with meat.

Below is a detailed, step‑by‑step guide to making restaurant-quality cold sesame noodles at home, plus substitution tips and variations.


What Are Chinese Cold Sesame Noodles?

Cold sesame noodles (often associated with Sichuan-style cold noodles and New York–style Chinese takeout) are wheat noodles tossed in a savory, slightly sweet, creamy sesame sauce. The key flavors come from:

  • Toasted sesame paste or tahini
  • Soy sauce
  • Vinegar
  • A touch of sugar
  • Aromatic oils (like sesame oil and optional chili oil)

They’re usually garnished with cucumber, scallions, sesame seeds, and sometimes shredded chicken or other toppings.

Ingredients for Cold Sesame Noodles

1. Noodles

You can use:

  • Chinese wheat noodles (fresh or dried, “oil noodles” or “lo mein” style)
  • Dried lo mein or thin egg noodles
  • Spaghetti (a common and effective substitute at home)

Recommended amount (serves 2–3 as a main, 3–4 as a side):

  • 250 g (about 9 oz) noodles

2. Sesame Sauce (Core Dressing)

Whisk together:

  • 3 tbsp Chinese sesame paste (preferred) or tahini
  • 1½–2 tbsp soy sauce
  • 1½ tbsp rice vinegar or Chinese black vinegar
  • 1–2 tbsp sugar (start with 1; adjust to taste)
  • 1 tbsp toasted sesame oil
  • 1 tbsp neutral oil (e.g., canola, peanut) – helps with silky texture
  • 1–2 cloves garlic, very finely minced or grated
  • 1–2 tsp chili oil or chili crisp (optional but recommended)
  • 2–5 tbsp water (to thin the sauce to a pourable consistency)

Tip: Chinese sesame paste (zhīma jiàng, 芝麻酱) is thicker and more intense than tahini. You’ll usually need a bit more water to loosen it. See more on Chinese sesame paste.

3. Vegetables & Garnishes

Use what you like, but classics include:

  • 1 small cucumber, cut into thin matchsticks (julienned)
  • 2–3 scallions, finely sliced
  • 1–2 tbsp toasted sesame seeds
  • Fresh cilantro leaves (optional)
  • 1 small carrot, julienned (optional but adds color and crunch)

4. Optional Protein Toppings

For a more substantial meal:

  • 1 cup shredded poached chicken or leftover roast chicken
  • Or: strips of pan-fried tofu, baked tofu, or seitan for a vegetarian/vegan option

Step-by-Step: How to Make Chinese Cold Sesame Noodles

Step 1: Cook the Noodles

  1. Bring a large pot of salted water to a boil.
  2. Add the noodles and cook until just al dente (firm but cooked), following package time but checking 1–2 minutes early.
  3. Drain immediately.
  4. Rinse under cold running water to stop cooking and cool the noodles.
  5. Drain very well, then toss with 1–2 tsp neutral oil to prevent sticking.

Avoid overcooking: slightly firmer noodles hold up better in sauce and after chilling.

Step 2: Make the Sesame Sauce

In a medium bowl:

  1. Add sesame paste (or tahini), soy sauce, vinegar, sugar, sesame oil, neutral oil, and garlic.
  2. Whisk until it starts to come together. It may look thick or seize at first.
  3. Gradually add water, 1 tbsp at a time, whisking after each addition.
  4. Stop when the sauce is smooth, glossy, and pourable, like heavy cream or a loose peanut butter sauce.
  5. Taste and adjust:
    • More vinegar for brightness
    • More sugar for balance
    • A pinch of salt or extra soy sauce if needed
    • Chili oil to your preferred spice level

A well-balanced sauce should be nutty, savory, slightly sweet, and tangy, with a lingering sesame aroma.

Step 3: Prep the Vegetables & Toppings

While the noodles cool:

  1. Cucumber: cut into thin matchsticks.
  2. Carrot (if using): julienne.
  3. Scallions: slice thinly on the diagonal.
  4. Protein (if using): shred chicken or slice tofu into thin strips.
  5. Sesame seeds: lightly toast in a dry pan over low heat until fragrant (1–2 minutes).

Step 4: Toss the Noodles

You can dress the noodles in a large bowl or assemble individual servings.

  1. Place the cooled noodles in a big mixing bowl.
  2. Pour in about ⅔ of the sesame sauce to start.
  3. Toss thoroughly with chopsticks or tongs until every strand is evenly coated.
  4. Add more sauce as needed; you want them coated but not sitting in a puddle.
  5. Taste and adjust:
    • Add extra chili oil if you like more heat.
    • Add a drizzle of vinegar or lime for extra brightness if desired.

At this point, you can either:

  • Serve immediately, or
  • Cover and chill for 30–60 minutes for deeper flavor (sauce may thicken slightly in the fridge; you can revive with a splash of water or a bit more sesame/neutral oil when serving).

Step 5: Plate and Garnish

To serve:

  1. Divide sesame-coated noodles into bowls or plates.
  2. Top with:
    • Cucumber and carrot matchsticks
    • Shredded chicken or tofu (if using)
    • Sliced scallions
    • Toasted sesame seeds
    • Cilantro leaves (optional)
  3. Finish with:
    • A spoonful of chili oil or chili crisp on top (for color and heat)
    • An extra drizzle of sesame oil if you like a stronger sesame aroma

Tips for the Best Cold Sesame Noodles

1. Choose the Right Noodles

  • Fresh wheat noodles have the best chewy texture.
  • If using spaghetti, cook it slightly shy of the package time and rinse thoroughly.
  • Avoid overly soft noodles; they turn mushy when mixed with sauce.

For background on wheat noodles, see Noodle on Wikipedia.

2. Balance the Sauce

Taste as you go. A classic Chinese cold noodle dressing is all about balance:

  • Saltiness from soy sauce
  • Acidity from vinegar
  • Sweetness from sugar
  • Richness from sesame paste and oil
  • Heat from chili oil

If it tastes dull, it usually needs more vinegar or a touch more salt/soy. If it’s too sharp, add a bit of sugar or water.

3. Don’t Skip the Rinse

For cold noodles, rinsing:

  • Stops cooking
  • Removes excess surface starch
  • Keeps noodles bouncy instead of clumpy

After rinsing, drain thoroughly and slick with a small amount of oil.

4. Make Ahead & Meal Prep

Cold sesame noodles store well, making them ideal for lunch boxes and make-ahead dinners.

  • Store dressed noodles in an airtight container in the fridge for up to 2–3 days.
  • The sauce can thicken in the fridge; loosen with:
    • 1–2 tbsp water, or
    • A mix of water + a bit of sesame/neutral oil, then toss again.

Keep fresh toppings (cucumber, herbs, etc.) separate until just before eating to maintain crunch.

Common Variations

1. Sichuan-Style Spicy Sesame Noodles

For a more Sichuan-inspired flavor:

  • Add 1–2 tbsp chili oil with sediment (like Lao Gan Ma or homemade) to the sauce.
  • Add ½–1 tsp ground roasted Sichuan peppercorns for a numbing (má) sensation.
  • Use Chinese black vinegar instead of rice vinegar for deeper flavor.

Learn more about the regional flavor profile at Sichuan cuisine.

2. Peanut-Sesame Noodles

If you love peanut flavor:

  • Substitute 1–2 tbsp of the sesame paste with smooth peanut butter, or
  • Add 1–2 tbsp peanut butter in addition to the sesame paste.

Adjust water and vinegar slightly, since peanut butter can be thicker and sweeter.

3. Vegetarian & Vegan Cold Sesame Noodles

The base recipe is easily vegan if:

  • You use plant-based noodles (most plain wheat noodles are vegan; check labels).
  • You avoid any fish sauce or oyster sauce additions.
  • Use tofu, edamame, or seitan as protein instead of meat.

You can increase plant protein by adding:

  • Boiled edamame
  • Tofu puffs
  • Roasted peanuts or cashews for crunch

4. With Shredded Chicken (Bang Bang–Inspired)

Add shredded, poached chicken for a dish reminiscent of bang bang chicken (bàng bàng jī):

  • Poach chicken breasts or thighs in lightly salted water with ginger and scallion until just cooked.
  • Let cool, then shred into fine strips.
  • Pile on top of the noodles and spoon extra sesame sauce over the chicken.

For background, see Bang bang chicken.


Frequently Asked Questions

Can I use tahini instead of Chinese sesame paste?

Yes. Tahini is made from hulled sesame seeds and is often lighter and more fluid. Chinese sesame paste is usually darker and made from toasted seeds, giving a deeper, roastier flavor.

If using tahini:

  • You may need slightly less water to thin it.
  • For a deeper flavor, you can:
    • Add an extra ½ tsp toasted sesame oil, or
    • Lightly toast some sesame seeds and blend them in.

Are cold sesame noodles Chinese or American Chinese?

The flavor profile and technique draw from Chinese cold noodle dishes, especially those from Northern China and Sichuan. However, the New York takeout style version popular in the West is a Chinese American adaptation that often leans sweeter and creamier.

You can adjust sugar and chili oil to lean more traditional (less sweet, more chili and vinegar) or keep it more takeout-style (sweeter, creamier).

Can I serve them warm?

Yes. While traditionally served cold or at room temperature, you can toss the sauce with slightly warm (not piping hot) noodles if you prefer. The sauce may become thinner when warm, so reduce the water slightly if serving warm.
